Pediatric Pericarditis

Pericarditis is an inflammation or infection of the pericardium, the thin sac (membrane) that surrounds the heart. There is a small amount of fluid between the inner and outer layers of the pericardium.

When the pericardium becomes inflamed, the amount of fluid between its two layers increases, compressing the heart and interfering with the heart's ability to function properly.

The following are the most common symptoms of pericarditis. However, each child may experience symptoms differently. Symptoms may include chest pain that:

Can be felt especially behind the breastbone, and sometimes beneath the clavicle (collarbone), neck, and left shoulder

Is a sharp, piercing pain over the center or left side of the chest that increases as the child takes a deep breath

A low-grade fever

Irritability

Fatigue

Loss of appetite

Irregular heartbeat

Children may not be able to describe that they have "chest pain" or be able to explain how they feel. Sometimes, non-specific symptoms such as irritability, loss of appetite, or fatigue will be all that the child is able to express.

The symptoms of pericarditis may resemble other medical conditions or heart problems. Always consult your child's physician for a diagnosis.

Your child's physician may have heard an abnormal heart sound called a rub, which occurs when there is irritation of the pericardial membranes. In addition to a complete medical history and physical examination, diagnosis for pericarditis may include:

Echocardiography (echo), a procedure that evaluates the structure and function of the heart by using sound waves recorded on an electronic sensor that produce a moving picture of the heart and heart valves
